Be it known that we, Riemen Atrfnrsrns BURY and ROBERT MAURICE BIDELMANitt zens of the' United States, residing at Adrian,y in the county of Lenawee and State 'of Michigan, have ini'ented certain new and useful Improvem en ts in Carb'u rctio'rs an d wedo h ereby declare that the following is a full, clear,` and exact description o't the inyention,wl1ich will enable others skilled in the art to which 1t appertains to ina-ke and use the same, reference bei u g had to th e accompanying drawings, and to the letters ot ret'erenee marked thereon, which` l'orm part of this specification.

Our invention relates to an apparatus for rendering natural gas ilIuini-mitng, and .has

for its object to so purity and enrich the Socalled natural gas now heine,` obtained in large quanti tiesi n certain parts of this country, andas yetprineipally used as a heat-producing agent, that it will be renderedavailahle as au illuininant.

as to not only purge the gasot those properties that are not illuininat ing but servel'o agreat extent to deteriorate the quality of the luminiferouf)` gases with which they may happen to bemixed, and then impregnating the gas with liydrocarlnnis.

In the aeeonipan yin g drawings, which form a part of this specification, Figure l. is a longitudinal vertical section. Fig. is a plan,

`Similar letters oi reference indicate similar parts throughout the views. A As is well known,natural gas essentially different from that vproduced from coal, oil, or any other of the liquid hydrocarbons, being deficient in olefant gas `as well as carbon. lhese propertiesI being the liest adapted for the evolution ol' light during their combustion, it is essential their proportions shall 'be increasef'l while. those gases that deterim'ate the. luminii'erou's power ol' the saine shall be removed'. y z

An analysis ol' natural gas shows the-pr`o. portion of :aix-,tenditl ol earbonie-aeid to one of oleiiant gas, with scarcely an appreciable per cent. of carbon. ln order to accomplish tho desired end,we connect the pipe D, leading from the source ot supply, with a U K We at tain these objects bypassj ing the gas through a receptacle so arranged dated February v10, 1889.

tank or earlnlretor, and, al'ler passingtlnrgas through a process ot' purification, pass the same thrtiugh a chamber filled with charcoal or tire-clay impregnated with any suitable hydrocarbon, by4 vwhich'the quality of hydrog carbon is increased and the gas thereby enriched toa degree io renderit a perfectilluminant.

Referringto the drawings, ll represents a 6o rectangular gas-tight box divided into compartments 3,113', and C by partition-walls L, M, and N, respectively. 'lhe compartments B and B are f or the reception of an alkaline solution, the intermediate compartment, C, being fille/d' lwith charcoal or lre-clay as densely packed as possible, for the double purposeotf regulating the fiow of the gas as it is forced therethrough by its own pressure, and of carburetiugthe same during its passage, the charcoal or tire-clay being thoroughllyT impregnated with any su itable Aliquid .h ydroearlmn, these ingredients being introduced through an orifice at the top, which is afterward closed by screw-cap K, the solution be- 75. ing introduced through tunnels G and G', provided with an ordinary cock or valve for 1 closing the same. 'Each compartment is provided with a cock for withdrawing the liquid contained therein, the end compartments, lB 8o and B', having cock H and H', respectively, and compartment C loeing .provided with cock J for withdrawing,any liquid hydroearbon that may beprecipitated. p

ln operation eoclc F is opened, allowing the gas to ow through pipe D to nearly thev bottoni of compartinelit/B, which being filled with an alkaline'solution it is purged of carboni@ acid by its ailinity with thesaine. The gas then passes through compartment C, pass- 9o ing through the densely-packed charcoal, or lire-clay, which may receive the gas at itsv initial pressure or at a reduced pressure., ne desired. .lu either event, all l`litmtuation is obviated by its passage through compartinent (l, I'Jeing thoroughly iinl'n'egnated with lrydroearlnin. The gas is carburetcd .to the desired stalnlard for illuminating .purposes and is again subjected to a washing or purifying processby being led between walls M and N roo and entering compartment B', also filled with an alkaline solution, whereby any deleterious matters that may by any possibility remain are absorbed, Iand the gasis ready to pass out through pipe E, (oook F being op en,) to

be used, as thus enriched and puried, as a perfect illuminanti. f 'lhe iLune produced by the gas when lthus treated is of `rreatbrillianey and has noradiation ot' heat therefrom. ln some portions of our c-ountr)v the gas flowing from the earth is colorless as well as odorless, involxfi'ng l: rreat danger from asphyxia by inhalation. By our method of enriching` the 'by surcharging' the same' with the volatile hydrocarbons this danger is obviated, as by their odor, should there be .an escape, it will be readily deterted before serions injury could result.

We would have it. understmnl that we have described our method and apparatus especially adapted to the use of natural gas. It vwillbe equally well adapted to the purification' and enriching' of any fluid desired to be Aused in combustion and deficient in any of the particulars herein recited.

Having described our invention, what We 'lhe herein-described apparatus for puri'lying, enriching, and controlling the pressure of natural gas and other aeritorm fluids, consistine; of a rectangular box, A, having'compart Tnents 13,1%', and C, each provided with means for ingress and egress, the parts B B being' filled with an alkaline solution, andthe part C filled with a densely-packed absorbent material impregnated with liquid 11 `ydrocarborr, two partition-walls dividing kthe box at one end, one wall rising from the bottom to near A the tap and the other extending from the top to near the bottom, .with a space between them, and a single wall rising from the bottoni to near the top dividing` it at the other end, as and for the purpose set forth.

. In testimony that we cla-im the foregoing as our o'wn invention We affix our signatures in presence of two witnesses.
